Abstract:
... An experiment was carried out to study direct and indirect responses to selection in the Angora rabbit. There were two selection lines, one selected for high fleece weight and the other for low fleece weight. Data from 669 female rabbits born in 1994-2001 and having produced a total of 2923 harvest of wool were analysed to quantify the correlated responses to selection. By 2001, there had been eig ...

Abstract:
... The effects of heat processing (roasting and steeping) on nitrogen (N) fractionations, ruminal degradation and intestinal digestibility of N and amino acids (AA) in two Iranian whole soybean cultivars (Sahar and Williams) were determined using two ruminally fistulated and two intestinally cannulated Holstein steers by nylon bag techniques. The seeds were roasted at 140 to 145 °C using a drum roast ...

Abstract:
... Recent studies have shown that l-carnitine supplementation of sows during pregnancy and lactation increases their reproductive performance, but the optimum supplementation level has not yet been determined. In this study we investigated the effects of supplementation of 25 and 50 mg l-carnitine/kg on traits of reproductive performance of sows in production stocks. A trial with 2118 sows was conduc ...
